    Auscultation. The impulse is strong, but li- mited in extent; only slightly raising the head, and soon lost beyond the precordial region. The /iist sound is dull and prolonged. The second. sound is very feeble over the heart itself, but may be detected under the sternum, and in the larger vessels. SIMPLE DILATATION. Externally the action of the heart is seldom perceptible, and no impulse is conveyed to the hand. The precordial region is natural. Percussion. There is a loss of sonority over a larger surface than usual, but with less resistance than in cases of hypertrophy. Auscultation. The action of the heart is only slightly felt, and at once gives the impression of diminished power. The impulse is weaker, brisker, and lower than usual. The first sound is clearer and shorter; becoming in advanced cases flapping and valvular like the second, and even inaudible, when the parietes are much enfeebled. The se- cond sound is more extensively heard in the pre- cordial region than usual, becoming weak and distant in extreme cases. Both sounds are widely transmitted over the thorax, and their loudness is not materially diminished by distance from their point of origin.
